title: Metabolism of carbohydrate in alimentary tract of reindeer in winter.
abstract: The study was conducted on six reindeers in December. It was established that concentration of reducing sugars in the chyme of jejunum increases substantially (6 times in comparison with abomasum), whereas concentration cellulose, on the contrary, decreases (4.5 times). The maximal increase of monosaccharides in the small intestine testifies to formation of metabolic fund of sugars in this part of the alimentary tract due to high degree of polysaccharides hydrolysis of exogenous, as well as endogenous, microbial formation. Obtained data assume that the need of the reindeer for glucose is provided for not only by gluconeogenesis as it was considered before, but also by absorption of monosaccharides from the alimentary tract.
